Description
Technical Field
[0001] The utility model relates to the technical field of valves, in particular to a dual-flow type simple valve. Background Art
[0002] Valves are common mechanical structures that can be found in faucets, gas stoves, and other locations. Taking the valve in a faucet application scenario as an example, the valve needs to withstand frequent reciprocating rotation during its service life to achieve water flow regulation. The traditional valve is connected to the faucet main structure through a threaded structure. Its frequent reciprocating rotation will continue to cause its own wear and looseness, and quickly shorten the service life of the valve. At the same time, a large number of reciprocating rotation processes are not necessary, but are fine-tuning when the flow is too large or too small. The fundamental reason is that the traditional valve is not accurate in regulating the flow. Based on this situation, how to achieve accurate regulation of the flow at the faucet position while avoiding wear, looseness, and even shortening of the service life of the valve caused by frequent rotation is becoming an increasingly urgent problem that relevant technical personnel need to solve.

The inner lower sealing block 18 moves out of the inner hole 11 first, and water starts to flow out of the inner hole 11. If the flow rate can meet the needs of the user at this time, stop turning the knob 1. If the flow rate is too small to meet the needs of the user at this time, continue to turn the knob 1 until the slider 13 moves to the highest position of the slide groove 7. During this process, the outer lower sealing block 17 moves out of the outer hole 12, and the outer hole 12 starts to flow out at the same time as the inner hole 11. The flow rate increases and can meet the needs of the user. After the user finishes using the water, turn the knob 1 in the opposite direction until the slider 13 moves to the lowest position of the slide groove 7 again, and the inner hole 11 and the outer hole 12 can be closed again by the inner sealing block 10 and the outer sealing block 9.
